Vintage Insert Refractor Bowl For Holophane 20" wide BEEHIVE Industrial Light MCM

Vintage industrial prismatic glass refractor bowl removed from an original beehive / high-bay light fixture. This is the inner drop-in refractor lens that sits in the center opening of reflector-refractor assemblies and helps diffuse and direct light downward while reducing glare. Heavy pressed glass with classic vertical and radial prism pattern consistent with early to mid-20th century industrial lighting. Measures approximately 5 3/4 inches wide across the top opening and 6 1/4 inches in overall length. Good vintage condition with no major cracks observed. May show normal age-related wear such as minor flea bites on the rim, light surface scratches, or small manufacturing bubbles typical of this type of glass. Please review all photos closely for exact condition details. This style is a gravity or rest-in mount refractor with no hardware and fits many industrial beehive and factory pendant fixtures. Ideal for lighting restoration, replacement use, or art projects. The last photo was only for reference lamp not included. Inside borders are sharp because it was manufactured as a stationary industrial item.
